It's already been confirmed that Sledgehammer Games(ex-Dead Space devs) & Raven Software are the ones working on MW3. Not yet sure if they are going to be credited as being on the IW team, but I 'm sure the name "Infinity Ward will be there. If you put a name like Bungie, Rockstar, or Infinity Ward on a game, better believe the game WILL push copies, regardless if the game sucks. These are the top developers most people know about, well respected and have always came out with great games, so people are going to buy from them.
